Telecomsoft was established in 1984 as the games publishing arm of British Telecom (BT). It operated three distinct labels: Firebird for budget and mainstream releases on the C64 and ZX Spectrum; Rainbird as a premium label for ambitious titles on 16-bit machines and advanced 8-bit platforms; and Silverbird from 1988 for budget re-releases of the back catalogue.
The catalogue is remarkable. Elite - the open-world space trading masterpiece by David Braben and Ian Bell - was published by Firebird on the C64 in 1985, two years after its original BBC Micro release. Rainbird brought Carrier Command (98% in The Games Machine), Starglider and Starglider 2 by Jez San, and the Magnetic Scrolls interactive fiction catalogue including The Pawn and The Guild of Thieves.
In 1989 British Telecom sold Telecomsoft to MicroProse, ending an extraordinary five-year run. The labels ceased publishing but their games endure - Elite spawned a franchise still alive as Elite Dangerous, and the Rainbird library remains a touchstone of 16-bit era design.
